Installation/De-installation
Commissioning and Functional Check
Do not touch live parts
The main fuse must be inserted to put the meter into operation and for the
functional check. Without terminal cover there is a danger of contact with
the terminals. Touching live parts is a danger to life.
The installed meter should be put into service and checked as follows:
4.5
1.
Insert the corresponding main fuse. The meter is on.
2.
Check whether the display appears correctly (no error message) and
with no load connected that the anti-creep indicators are constantly on.
3.
Connect a load and check whether the anti-creep indicator for active
energy disappears.
4.
Check whether the disconnector (if present) works according to the
functionality specified for your application.
Disconnecting the Meter
Remove main fuse before disconnecting
The connecting wires at the place of installation must not be live when
removing the meter. Touching live parts is dangerous to life. The corresponding main fuse should be removed and kept in a safe place until work
is completed, so that it cannot be replaced by anyone unnoticed.
For ZCF100xB: Do not use the disconnector as a main switch for
disconnecting purposes! The meter remains connected to the mains!
Remove the meter from the network as follows:

If there is voltage, remove the main fuse.
5.
Remove the connecting wires of the AMR Module, if available.
6.
Loosen the terminal screws of the phase and neutral connecting wire
with a suitable screwdriver and withdraw the wires from the terminals.
